Yes it is The hypotenuse is 10 cms long.
Because its a right angled triangle ( 90 angle) the hypotenuse will be 10 cms long - it will obey the Pythagoras theorem:-
10^2 = 8^2 + 6^2
There is only one right angled triangle with these measurements but there are many of them which have sides in same ratio
for example
3, 4 and 5
9,12 and 15
12, 16 and 20 and so on..
